CIRCUIT-CLOSING DEVICE.

Specification of Letters Patent.

Patented Oct. 17, 1911.

Original application filed October 11, 1909, Serial No. 522,009. Dividedand this application filed February Be it known that I, VVORTI-IINGTONE. MORTON, a citizen of the United States, residing at Shelby, in thecounty of Cleveland, State of North Carolina, have invented certain newand useful Improvements in Circuit-Closing Devices; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to circuit closing devices and is particularlyadapted for use in connection with machines which receive materialin'continuous form and are provided with electrically controlled stopmotions.

The object of the invention resides in the provision of a device of thecharacter named which will automatically close the circuit controllingthe stop motion when the supply of material passing to the machine fromany given head has become exhausted.

For a more detailed understanding of the construction and operation ofthe invention same will be described with reference to the accompanyingdrawings, wherein like char actors of reference denote correspondingparts in the several views; and in which Figure 1 is a rear elevation ofa standard ribbon lap machine with the invention incorporated; thecentral portion of the machine being broken away; Fig. 2, an endelevation of a portion of the machine, shown in Fig. 1, illustrating thedetailed construc tion of the lap spool and the lap rolls; and

the electrical connection for closing the circuit of the stop motion ofthe machine when the supply of material from any given lap spool hasbecome exhausted; and Fig. 3, a partial section on the line 3-3 of Fig.1.

Referring to the drawings, A and A represent respectively the samsons ofa ribbon lap machine, said samsons being connected at their upper endsby a beam A which is adapted to support directly and indirectly certainelements of the machine disposed thereabove. Connecting the samsons Aand A intermediate their ends is also a cross beam A and journaled inthe samsons A and A between the crossbeam A and the beam A is the maindrive shaft 15 of the machine. A loose pulley 16 and a fixed pulley 17are mounted on said drive shaft and a power transmitting belt 18 isadapted Serial No. 608,607.

which latter is pivotally mounted upon the machine at a suitable point.The belt 18 is further adapted to be shifted from the pulley 17 to thepulley 16 through the instrumentality of a stop motion S which iselectrically controlled and designed to be automatically operated whenthe supply of the material from any of the lap rolls of the machinebecomes exhausted. Said stop motion includes a normally restrainedthrust rod 25 which is adapted to travel in a guide bracket 23 securedto the cross beam A and in a slot 24 formed through the samson A, theouter end of said thrust rod 25 being adapted for engagement with thearm 19. A spring 26 has one end secured to said thrust rod and the otherend to the samson A; said spring constantly tending to move said thrustrod to shift the belt 18 from the fixed pulley 17 to the loose pulley16. Said 'As the construction and operation of the mechanical elementswhich effect the release of the thrust rod 25 to stop the machine isfully described in my co-pending application, filed October 11, 1909 andserially numbered 522,009, of which this application is a division, adetail reference thereto will be omitted herein; it being sufficient tosay that when the circuit which controls the operation of the mechanicalelements for automatically releasing the thrust rod 25 is broken, themovements of said elements will fail to elfect a release of the thrustrod, while on the other hand when said circuit is closed the movementsof the mechanical elements of the stop motion are so altered that thethrust rod is immediately released from engagement with the bracket 23and the machine stopped.

The circuit which is adapted to be closed when the supply of material isexhausted from any of the lap rolls of the machine is supplied by agenerator G one pole of which is connected to the machine so that thecurrent passing therethrough travels by way of the metallic uninsulatedportions of the machine and through ashaft 48 which carries the laprolls 49. Each of the lap rolls 49 is constructed of wood and has ametallic annular band 50 secured to the periphery thereof, whichconstitutes one terminal of the circuit controlling the stop motion;said band being in turn electrically connected with the shaft 48 throughthe medium of screws 51 and 52, which extend transversely through theroll 49. The remainder of the circuit controlling the stop motion isformed by connecting the other pole of the generator Cwith an electricalconductor 79, which latter is in turn connected to a rod 53 mounted onthe machine but suitably insulated,

therefrom. It will of course be understood that the electricallyoperated portions of the stop motion S are suitably located in theconnections 79 so that when the circuit, of which said connections forma part, is closed, said stop motion will be operated. A spring finger 54is mounted on said rod 53 and is adapted for continuous contact with ametal band 55 which is secured to the periphery of another lap roll 56,said last mentioned lap roll being in turn mounted on a shaft 57insulated from the machine;

said band 55 thereby constituting the other terminal of'the circuitwhich controls the stop motion. Supported upon the lap rolls 49 and 56is the lap spool 58 which carries the supply 59 in the usual ribbonform. The periphery of the spool 58 is provided with an annular band 60which is adapted to simultaneously contact with the band 50 of the roll49 and the band 55 of the roll 56 when the supply is entirely removedfrom said spool, thereby closing the circuit and instituting theactuation of the stop motion.

While the invention has been described as applied to a ribbon lapmachine, it will be evident that it is not confined to this particularclass of machine, same being ap licable to any machine provided with ane cotrically operated stop motion and which receives its material incontinuous form from a roll orspool.

What is claimed is:

1. The combination with electric circuit and a stop motion adapted to beautomatically operated by the closing of said circuit of a machineadapted to receive its work in the form of a continuous lap, saidmachine including a pair of electrical conductive lap rolls forming theterminals of said electric circuit and an electric conductive lap spoolsupported by said rolls and adapted to receive between it and the laprolls the supply of material, whereby when said supply is exhausted thespool will close the circuit between the rolls.

2. The combination with an electric circuit and a stop motion adapted tobe automatically operated by the closing of said circuit, of a machineadapted to receive its work in the form of a continuous lap, andincluding a pair of lap rolls each of which carries a terminal contactof said circuit in the form of an annular metallic band, a lap spoolsupported by said rolls, the supply of said spool being interposedbetween the rolls and said spool during the feeding thereof, and anelectric conducting element carried by said spool adapted to conduct theterminal contacts carried by the lap rolls when the supply of lap isexhausted from said spool.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
